By manufac- turing its own cylinders and valves, HIAB maintains strict quality con- trol over its products. Morgan Crane Company provides comprehensive service support in- cluding technical assistance at cus- tomer locations worldwide. NABRICO Circle 42 on Reader Service Card An all-new hand winch specially designed for use on barges and tow- boats, and for other winch applica- tions where significant holding ca- pacity is required, is the latest inno- vation in deck fittings from Nash- ville Bridge Company (NABRICO) of Nashville, Tenn. Of all-steel construction, the mini-profile design winch has a 40- ton holding capacity. In addition, both right- and left-hand models are available, promoting increased safe- ty for the operator. A feature of the winch that should make it especially attractive to the marine industry is the accompanying "D" ring that al- lows the unit to be swivelled a full 180 degrees, providing a significant degree of maneuverability. Gears, side plates, ratchet, and shaft are precision-machined to in- sure proper gear tooth engagement and minimize wear. Large bronze bushings with grease fittings on all shafts add to the useful life and dependable service of the winch. The new hand winch utilizes many features of the original NA- BRICO hand winch, including a quick-release action, a handwheel for fast take-up, and a foot brake for run-out control. In addition, many parts for the new winch are inter- changeable with parts for other NA- BRICO winches, making repair or replacement easier, and all parts are available from Nashville Bridge Company or many of its distribu- tors. Addition of this mini-profile hand winch is said to make NABRICO the only full-line manufacturer of deck fittings in the industry, and it is a complement to their existing line of hand, hydra-electric and electric winches, hatch covers, kev- els, bitts, buttons, and other prod- ucts. NABRICO is a wholly owned sub- sidiary of The American Ship Build- ing Company of Tampa, Fla. The company has been in the marine field for more than 70 years, and offers a complete line of deck hard- ware for towboats, barges, and ter- minals serving the marine industry. With plants in Nashville and Ash- land City, Tenn., NABRICO is a major supplier of marine deck hard- ware to the entire industry. The company pioneered in the design and construction of much of the modern equipment used on the in- land waterways today. NATIONAL CRANE Circle 43 on Reader Service Card For medium- to heavy-duty lift- ing jobs afloat or ashore, National Crane Corporation's Marine Lifting System provides a choice of pedes- tal-mounted, telescoping hydraulic cranes and accessories that will complete any task quickly and effi- ciently. National marine cranes are a fa- miliar sight on ships and fishing ves- sels, on docks and offshore plat- forms, at oil terminals, and in many other marine applications. The wide selection of boom lengths and lifting capacities, combined with the quali- ty engineering features standard on all models, has made them suitable for any saltwater application. The choices start with the eco- nomical Marine 200, and range up- ward through the 400A, 600A, and 800A series. The 200, with a rated capacity of 10,700 pounds and 28- foot hydraulic boom is suitable for use on smaller boats and barges, for general-purpose dockside and ter- minal work, and on offshore plat- forms. For medium duty, there is the 400A, with 16,000 pounds rated ca- pacity and 55-foot boom; its depen- dability has made it a workhorse of fishing fleets. The 600A fills the medium- to heavy-duty range with its 25,000-pound maximum lift and 66-foot boom. With 35,000 pounds rated capac- ity and 75-foot, four-section hy- draulic boom, the Marine 800B has become a favorite for heavy-duty lifting where long reaches are re- quired. Its extra-solid construction means more time on the job and less downtime, even under extreme duty. Regardless of size, all National marine cranes share design features to boost reliability and perfor- mance. Maximum strength and ca- pacity are achieved through the use of computer-aided box section boom design. The boom sections are built of four high-strength, low-alloy members. Weight is cut without sac- rificing strength by use of thicker top and bottom plates. The low- hydrogen welds on corner seams are ultrasonically tested for proper pen- etration. The boom extends sequen- tially, an advance National intro- duced to the industry. Mechanical, not hydraulic, locks provide greater reliability without wasting hydrau- lic power. Full marine conditioning is stan- dard on National telescoping cranes. External surfaces are sand blasted, coated with inorganic zinc primer, painted, and covered with a durable chlorinated rubber topcoat. Interior surfaces are primed and painted to help prevent corrosion. All lift cylinder rods and boom pivot pins are stainless steel to withstand saltwater and chemical environ- ments. Continuous welds are used wherever possible to prevent corro- sion in crevices. These marine cranes, like all Na- tional telescoping cranes, are equip- ped with standard anti-two-block- ing systems to prevent crane dam- age. Precision rack-and-pinion tur- ret rotation is standard on the Ma- rine 200, while the larger models use planetary rotation gearboxes. NATIONAL SUPPLY Circle 44 on Reader Service Card A cargo-handling barge designed to accept a National Supply Compa- ny continuous lift jacking system enables the operator to readily con- vert the barge into a stable platform for loading and unloading. The barge uses a rack-and-pinion jack- ing system originally developed by National for offshore drilling and production platforms. With the legs jacked up, the barge retains its mobility and can be easily towed between sites. Once in loca- tion, the barge is jacked up to create a stable platform at various deck levels. The jacking system, which has a smooth, continuous lifting movement, uses an arrangement of horizontally opposed pairs of pin- ions that provide positive engage- ment with a preeision-cut, double- sided rack. The National jacking system has been used in 18 different rig designs and is offered by more than 30 ship- yards around the world. Literature available from National contains specifications for various unit ar- rangements, tensile properties for its components, and a description of other features, including pushbut- ton control operation and various safety features. Individual leg control is accom- plished at a central console, where the operator can operate all legs individually or simultaneously, with mixed hull-up and hull-down opera- tions. Each climbing pinion has an individual gear motor and gear train drive, with each motor having an electromagnetic-released, springset, fail-safe multi-disc brake. NAUTILUS CRANE Circle 45 on Reader Service Card Nautilus Crane & Equipment Corporation, headquartered in Re- serve, La., has completed fabrica- tion and testing of one of the most unique offshore cranes ever de- signed. This Model 380L lattice boom crane has an 80-ton capacity and is mounted on the Nautilus Model 300P rolling gantry platform. The 380L can traverse the plat- form on two separate and perpen- dicular sets of longitudinal beams, and has the special capability to move from one set of beams to the other. This permits the single crane to accomplish tasks that would nor- mally require two or more separate cranes. The crane is capable of traveling with loads along the beams at the rate of 40 feet per minute. Position- ing of the rolling gantry requires that the operator simply switch the hydraulic system from the propel to the hoisting operation. During a lift- ing operation, the rolling gantry cannot be moved (release of rolling gantry propel lever automatically slows travel and sets brakes). The primary and secondary retaining rollers are always engaged, and all crane functions are operative while the gantry is stopped. The 380L is powered by an on- board Caterpillar diesel engine.
